Cases 2 and 3 should sound quite similar, although we need not aim at exactly identical results. Case 3 is cheap to synthesize, because it can use the same input signal as case 1. This shows that different dynamic levels can be produced with one excitation signal, when the timbre control filter is used appropriately.

The following sounds demonstrate how various plucking styles can be simulated with the current synthesizer (for more details, see the Section 3 of the paper)
